Sampling device and sampling method for low-concentration total particulate matters in flue gas of thermal power plant |
| abstract |
The invention provides a sampling device and a sampling method for low-concentration total particulate matters in flue gas of a thermal power plant, which are suitable for detecting the emission condition of the total particulate matters discharged by the flue gas after ultralow emission modification or flue gas plume treatment modification and detecting the particulate matter removal performance of equipment. The sampling device mainly comprises a sampling device, a condensing device, a dehumidifying device, a metering device and a sampling pump which are sequentially arranged along the flow direction of flue gas; the sampling device comprises a sampling head and a heating sampling gun; the sampling head is formed by combining a sampling nozzle and a first-stage filtering membrane; a secondary filtering membrane is also arranged between the condensing device and the dehumidifying device; the condensing device adopts a two-stage series structure, and the two-stage condensing device is respectively provided with a water bath temperature control device; and a reinforced phase change system is arranged between the two stages of condensing devices and is used for adding water vapor into the flue gas entering the rear stage condensing device, increasing the humidity of the flue gas and improving the total particulate matter trapping rate. The device can realize scientific, accurate and comprehensive test of the total particles. |
